The outages are making some worry about whether Verizon’s vaunted network can truly handle a large number of new subscribers using iPhones, especially since Verizon will offer iPhone users a $30/month unlimited data plan. Epstein speculated the outages were due to Verizon testing the network in advance of the iPhone launch.

Verizon has promised that its network is prepared to take on the new traffic. “We’re not going to have any flaws on the execution of the iPhone launch,” Chief Financial Officer Fran Shammo said.
